Rock Island daily Argus. (Rock Island, Ill.) 1886-1893, 1887-12-22

SGrand total estimated cost. s. or, 329 %
The expense on the first mile is made
principally by the cost Of the lock at the
upper end, for which 1915, 600 is the esti-
mate. The nearly $40, 900 in the elev-
enth fractional mile is accounted for by |
the double chsmbered lock at the entrance |
to the pool. for which $500, 900 is thought |
to be about the right figure. Between
these two locks there will be seen to be
some remarkably cheap miles. the eighth
being estimated as low as $4,000. The
items of expense below the entrance to
the pool are made up as follows: Rock
excavation in the pool. $44, AS; earth,

where it is proposed the canal shall go

excavation across the Island. $21. 900;
embsnkment for a south wall for the
canal, the south bank of the Island form.

600. without adding thereto the 10 per
cent for contingencies. which appears in
the total above. showing the expense for
locks to be not very far from one-half of
the total estimate. These locks are in>
tended for the use of the largest stesm>
boats.
Mr.. Lewis furthermore outlined the
course of the proposed canal. 1t is to
start, he said above the mill and mill
dam at Rapids City, in the deep pool at
the head of the rapids, at which poin,
there is lock with double gates. The
} canal cuts around the Touring mill on the
land side, through the village Of Rapids
} City. and turns into the river again before
leaving the village. From this point tt
